I try to use an GregorianCalendar as Input Field.
Therefore I have written an validator for Input format (dd.MM.YYYY), and an Converter to get from the validated String the Calendar.
In my jsf page:

The Problem: The Converter is called before the Validator, so this makes no sense.
Is it possible to process the validator and after that the Converter?
I tried another way without an validator, so the validator part in the converter before converting.
If there is an validation Error, I throw an ValidatorException message.
The Problem is, that I can't use the message tag for writing the error to the output JSF file. It is ignored, and I get a page sized error.

Any suggestions?
